CHECKLIST B (Paragon-3) General Check out
Paragon3 units are set and characterized at the factory to optimize performances.
It is not recommended to try readjusting units unless it is really required.
Misadjusting a unit may result in significant performance losses.
The proposed adjustments in the "IF NOT?" column below, should be tried ONLY if system data perform-
ance degradation is noticed combined with out-of-tolerance items.
